In the Norstar riometer data archive on aurora.phys.ucalgary.ca
sometimes there is more than one file per day/site (i.e. from
different "streams" or "versions") e.g.

chu_canopus_dcp_rio_20050101_v0.txt
chu_rio_20050101_v1a.txt

chu_canopus_dcp_rio_20051025_v0.txt
chu_norstar_rio_20051025_v0.txt

As agreed with NORSTAR, on the CSSDP we put only one file per day/site
to the database, selected according to the following priority:
 
sss_norstar_rio_yyyymmdd_v1a.txt
sss_canopus_dcp_rio_yyyymmdd_v1a.txt
sss_rio_yyyymmdd_v1a.txt
sss_norstar_rio_yyyymmdd_v0.txt
sss_canopus_dcp_rio_yyyymmdd_v0.txt
sss_rio_yyyymmdd_v0.txt

(I did not actually find all of these types in the archive so far, but
this is the rule in case they all exist.)

This directory keeps all the files that were in the NORSTAR archive
but have not been put to the cssdp database, because other file for given
day and site was put to the database.
